Description

Between regular clouds and the "big brown cloud" newt sat on NGC6888 for a spell. This is an 11.2 hour R/G/B/H/O with RGB each 71x60sec and H/O 24x600 sec. Just made the RGB in PI and did DBE using Ha to help guide for a very few background points. Then did color balance using stars as white point. Blended H/O using the simple PI script for that purpose. mlt noise reduction at linear stage then masked stretch partly and finished with curves. Made a blue color mask and slightly boosted the faint blue structure framing the nebula. TGV denoise.
